As your database environment continues to evolve, it can be challenging to keep up with all the solutions available. Open source databases are becoming increasingly popular, with over 90% of developers using at least one in their stack.

In this tutorial, we'll list 14 of the most popular open source databases and show their pros and cons to help you determine the best solution for your needs.
MySQL is the most famous and widely used open source database. As a relational database management system (RDBMS), MySQL structures data by organizing it into interconnected tables that users can access using SQL (Structured Query Language). The platform supports multiple storage engines such as InnoDB and MyISAM.
Example

While it is possible to interact directly with a MySQL database using a standalone client, MySQL is more often part of a software stack, such as LAMP. Due to its popularity, MySQL is the RDBMS of choice for web applications that require a database, such as WordPress, Joomla, and phpBB.
